To provide a superconducting coil capable of suppressing degradation of electrical characteristics, and to provide a superconducting apparatus using the same.
The superconducting coil includes: race track type coils each constituting, for instance, a stator coil 21; for instance, a stator core 23 arranged on inner peripheral surface sides of the race track type coils; and a set of magnetic flux line induction members 50 each facing a straight part of the race track type coil and a side of the stator core 23, having a length larger than that of the straight part of the stator core 23, and arranged to interpose the race track type coils. Magnetic flux 59 advancing from the inner peripheral surface side of the race track type coil to the outer peripheral surface side thereof passes through the magnetic flux line induction member 50, and leakage magnetic flux 58 leaking from the magnetic flux line induction member 50 advances in a direction intersecting the thickness direction of a superconductive wire constituting the race track type coil.
